Hi Charlie: I am sure that the cable that you have is what is called "flooded cable". It is just kind of sticky, not a liquid. It is just sticky enough to cause the braid and foil to get stuck on ev

I have been using a Yaesu FT-1000D for about 15 years. If I had to buy another transceiver, it would be another FT-1000. The original APF was fantastic. After a BIG lightning strike, I sent it in for

Hello Jarda, The 7800 series of voltage regulators WILL oscillate ! If you have 100 to 500 mfd on the input and 0.1 mfd on the output, it will be stable. You can have as much capacitance on the inpu

Herb, thanks for your comments about Deaf stations. When Merv K9FD and I were at BY1QH in 1998. We worked a bunch of west coast and middle USA stations on 160. Nothing east of the Mississippi River

George: You are so right! When I first got on 160, I had a low sloper and no Amplifier. I found out very quick that combo didn't cut the mustard. I have 80 ft of Rohn 45G with a Telrex 20 meter 5el

Ed, I don't think that you have to worry about the losses in that length of RG6. It will be so low that you will not notice it. 73 Price W0RI _______________________________________________ Topband

I had an ANC-4 and I was not impressed with it. The MFJ 1026 seems to do much better. The MFJ has automatic switching RF sensing.but in their manual, they recommend not using this. They state that on

Steve: The MFJ 1026 comes with a small telescoping antenna that can be used as the "noise" antenna. It also contains a preamplifier for the "noise" antenna. The 1025 does not have this. In most case

Hi Merv: You might consider brazing the copper straps together. I think that even a better idea would be to clean the copper straps with 320 grit wet/dry sandpaper. Coat with "naolox" or a simular e
